Hydrosilylation of Pyridinealdehydes and Acetylpyridines Catalyzed by Caesium Fluoride in the Presence of 18-Crown-6

Goldberg, Yu,Rubina, K.,Shymanska, M.,Lukevics, E.

, p. 2439 - 2446 (2007/10/02)

Reactions of isomeric pyridinealdehydes and acetylpyridines with dimethylphenylsilane proceed readily in dichloromethane in the presence of catalytic amounts of CsF and 18-crown-6 to give silyl ethers of the corresponding pyridyl carbinols in good yields
